摘要
介绍了大芯径多模光纤。使用这种光纤，采用松套层绞式结构，制造了双钢带防鼠阻燃光缆．满足了客户的要求。试验研究了大芯径多模光纤（Ф500μm）二套工艺和光纤的余长．并与普通单模光纤（Ф250μm）二套工艺进行了对比。光缆的性能令人满意．已经用于传感领域。
Large- core muitimode fiber is introduced. A stranded loose tube cable with large core multimode fiber （200/230-37 μm） is developed. With double corrugated steel and LSOH sheath, the cable is rodent-resistant and flame retardant. Compared the process with normal single mode fibers （ Ф 250 μ m）, the process and excess in secondary coating with large core MMFs （ Ф 500 μ m） is studied. The cable is found to be satisfactory and now services in the application of sensor.
